The classical cobweb theorem is extended to include production lags and price forecasts. Price forecasting based on a longer period has a stabilizing effect on prices. Longer production lags do not necessarily lead to unstable prices; very long lags lead to cycles of constant amplitude. The classical cobweb requires elasticity of demand to be greater than that of supply; this is not necessarily...

The EU-FP4 project Cloudmap aimed to estimate new cloud-top products (heights, type, optical thickness, effective droplet size), especially for cirrus and contrail clouds from existing and new sensors, using three different techniques (brightness tem¬ perature with C02 slicing method, stereo-scopy and Oxygen A-band). These cloud-top products were validated using airborne sensor underflights, mu...

Introduction Lung protective ventilation, LPV, is recommended for ever wider patient populations, even those without primary lung disease. Low tidal volume ventilation is a first-hand remedy for LPV that is facilitated by dead space reduction. Inspiratory flow pattern affects gas exchange. In ARDS patients, it was recently shown that a long period during which inspired tidal gas is in contact w...

OH, N2, H2, and trans la t Laboratory experiments in which recombined CO, C02, D20, and 02 molecules desorb from surfaces in excited internal ional states are briefly reviewed. Unequilibrated distributions predominate from the principally catalytic-metal substrates so far investigated. and in some cases less than, wall-thermal; the velocity distributions generally vary with emission angle, with...

In the last 30 years, degree of pollution has been continuously increasing and chemical structure the
 atmosphere changed due to large amounts polluting emissions such as N0X, S0X, C02 other particles
 resulting from combustion, which lead destruction ozone layer, climate change, greenhouse effect
 or acid rain. Because price oil is increasing, degrading emissions
 exhaust g...

The importance of microorganisms to the mixed activities could be obtained. For this ruminant has interested an increasing number of reason, and because the pure culture approach nutritionists, particularly those in departments is time consuming, methods for studying the of animal science. In view of this interest of natural mixture have been developed. The inagricultural workers, it is surpris...

Recent work has emphasized that both glucose and acetate are important metabolites in the ruminant. Annison & Lindsay (1961) estimate that 33 % of expired C02 is derived directly from acetate in the fed sheep, and Annison & White (1961) find that, under these conditions, 23 % comes from glucose; both these values are sensitive to the nutritional state of the animal. Considerable quantities of b...

Moreira-Jacob (J. Bacteriol. 86:599, 1963) reported that 44 strains of Brucella suis were inhibited by safranin 0 in Brucella Agar (Albimi), whereas nearly all of 320 other strains of Brucella were not inhibited. Brinley-Morgan (World Health Organization, Brucellosis document , 246, 1963) examined the growth of more than 80 cultures on serum dextrose agar with added safranin 0, and found that a...
